MICHAEL LOFIUS, OF CHICAGO, ILLINOIS.

NON-BEFILLABLE BOTTLE.

Application filed June 10, 1907, Serial No. 378,177.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, MICHAEL LOFTUs, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Im provements in Non Refillable Bottles, of which the following is a specification.

This invention is a valve for non-refillable bottles, l'ieing particularly an improvement on the valve shown in my United States Patent No. 838085, dated December 11, 1906.

The object of the present improvement is to form an improved guard for the valve, to prevent the insertion of a wire or other implement for tampering with the valve, and also to provide means for quickly forcing the valve to its seat.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a vertical section of a bottle provided with the invention. Fig. 2 is a perspective view of a weight and guard. Fig. 3 is a section on the line 33 of Fig. 1.

Referring specifically to the drawings, 10 indicates the body of the bottle, and 11 is the neck thereof, provided with an internal annular flange 11, which forms the valve seat.

12 is a permanent stopper or bushing which is inserted and cemented in the mouth of the bottle neck and is provided with an opening 12- for a cork.

13 is a valve disk, which is made of rubber or any other suitahle material and which seats upon the flange 11. This valve has a hollow glass member or float consisting of a bulb 14 having a depending hollow stem 14 which extends through the valve disk 13 and is flanged at the lower end as at 14.

Located within the space in the bottle neck, above the valve, is a solid hall or weight which serves to quickly force the valve 13 to its seat whenever the bottle is tilted above the horizontal. This is an im provement over the construction shown in my patent referred to, in which the valve would not close unless the bottle were substantially vertical.

In the upper part of the bottle neck is a guard 15, consisting of a block of metal,

I glass or the like, confined loosely between an 1 upper perforated disk 17, which rests on an t annular shoulder 20, and a lower perforated disk 17 a which rests on an annular shoulder 1 16, formed in the bottle neck. The block 1 15 is irregular in shape, having curved grooves or depressions in its outer surface, l forming tortuous passages through which the liquid can flow out and air enter. The grooves in the block extend at angles to each other in the upper and lower parts thereof, extending in opposite directions from the waist or middle groove 15 which encircles the block, so that if a wire should be inserted through the upper disk 17 it would be guided by the grooves in such direction that it would be caught in the waist or middle groove 15 and would not find or pass through the perforations in the lower disk. Tampering with the valve by such means is therefore prevented, even by the use of a bent or flexible wire.

The valve opens or closes when the bottle is tilted, in substantially the manner described in my former patent, and the present improvements effectively prevent the insertion of any means to open the valve to per mit liquid to be forced or poured into the bottle.

1 I claim:

1 1. In a bottle, the combination with a valve in the neck thereof, of a guard coml prising upper and lower perforated disks in 1 the neck, and a block between the disks, having tortuous grooves in the sides thereof.

l 2. In a bottle, the combination with a l valve in the neck thereof, of a guard coinprising upper and lower perforated disks in l the neck, and a block between the disks hav- 1 ng a groove around the middle thereof, and grooves extending upwardly and downwardly therefrom at an angle to each other.

In testimony whereof I aifix my signature, in presence of two witnesses.

MICHAEL LOFTUS.
